FOOT WARMER FOR AUTOMBILES.

Application led February 3, 1920. Serial No. 356,088.

This invention relates to certain new and i useful improvements in foot Warmers Vfor automobiles, the object being to provide a foot warmer which is exceedingly simple and lcheap in construction andone which can be readily placed in position over the exhaust manifold `of an internal combustion engine in such a manner that the exhaust gases will heat the air in its passage therethrough and deliver the same into the body of the car.

-A still further object of the invention is to provide a heater which is formed of a sheet of metal bent into tubular form so constructed that' the same can be placed over the exhaust manifold of an internal combustion engine and clampedin position by the clamping means employed for attaching the manifold to the engine.

Another' object of the invention is to provide a novel form of cap having a grill work in order to form a register within the car.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claim.

In the drawings,

Figure 1 is a side elevation of a portion of an automobile partly broken away showing the application of my improved construction of foot warmer thereto.

Figure 2 is a vertical section through the foot warmer partly in elevation showing the manner of attaching the same; and

Figure 3 is a plan view of the cap showing the manner of securing the same in position within the foot board of the automobile.

In the drawings 1 indicates the body of the automobile, 2 the dash board, 3 the foot board, l1 the hood, 5 the radiator, 6 the internal combustionengine, 7 the intake manifold 'and 8 the exhaust manifold, the above description being given so thatlthe application of my improved construction of foot warmer can be readily understood.

My improved construction of foot warmer comprises a sheet metal drum 9 which 1a arranged over the vexhaust manifold 8 of the internal combustion engine and as herein shown is provided with a bell shaped end 10 to receive the air passing through the radiator 5 and it is of course understood that a circulation of air will be created through the drum by the fan or by the movement of the vehicle so that the air passing through the drum will be heated and delivered into the `body of the motor vehicle.

The rear end of the drum 9 extends through an opening formed at the junction of the dash board with the foot board and has secured thereon a cap 11 which is provided with a grill portion 12 and a flange 13l which is provided with openings through which screws 14 or the like are adapted to pass for securing the same to the foot board of the motor vehicle.

The drum 9 is formed of a sheet of metal bent into tubular form, having one of its longitudinal edges arranged under'- the exhaust manifold and the other longitudinal edge provided with apertured ears 15 through which the clamping bolts 16 employed for securing the manifold in position on the internal combustion engine extend so as to securely clamp the drum in position over the exhaust manifold as clearly shown. The drum forms an air chamber surrounding the exhaust manifold in such' a manner that the air in its passage therethrough is` heated by the exhaust manifold so that the hot air will be delivered within the body of the motor vehicle to which the device is attached and by placing the same in the foot board a .foot warmer is formed asI well as a heater. It is of course understood that the drum is so constructed that it embraces the manifold of the internal combustion'engine in such a mannerv that it can be readily applied or removed and while I have shown apertured earsl for securing the same in position it is of course under- -stoodthat these ears could beplaced under the clamping means of the manifold.

In order to provide means for controlling the exhaust of hot air `from the drum to the body of the car I arrange within the rear end of the drum afyalve 17 which is mounted on a stem 18 havlng an arm 19 which can be either operated` from the dash. as clearly shown or locked in its adjusted osition by a set screw or the like but it is o course un derstood that the preferred-manner trolling lthe valve is Jfrom the dash so that the occupants of the car can either close or open the valve.

From the foregoing description it will be seen that l have provided an exceedingly simply constructed foot Warmer which is mounted over the exhaust manifold of the engine and extends rearwardly through the dash board and foot board of the motor vehicle whereby the same can be readily applied by simply cutting a small opening in the foot and dash boards of the Vehicle.

What I claim is As a new article of manufacture, a foot warmer for motor vehicles comprising an .open ended drum, a cap arranged overl one end of said drum having an angularly disposed grill portion, said cap having an angular attaching flange, a valve stem extending'transversely through said ,drum adjacent said cap, a valve earried l by said stem and an operating arm fixed on one end of said valve.

lin testimony whereof I hereunto affix my signature in the presence of two' Witnesses.
